Hello devs ! I play Among Us since 2018 and i have 2 ideas. I think it should be fun to introduce this ideas.
Idea N1 : When the half of the crewmates are ghosts, the game gives to 1 player a role "The Guardian Angel" this role can put traps to the impostor and help the crewmates. Freeze the kill cold down for 5 seconds, alert a crewmate that is in danger, an ability called sacred shield that only has 1 use and you can give it to a crew member for a few seconds. The crew with the sacred shield doesnt know that have the shield. If the impostor try to kill a crew with the sacred hole the kill cold down reset and the sound of a sword breaking sounds to the impostor.
Idea N2 : It is the same but each ghost crewmate is assigned a crew member to take care of him.
Cheers!
